Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The Coco fatty acids 2-sulfoethyl ester, sodium salt is considered to be readily biodegradable. Coco fatty acids 2-sulfoethyl ester, sodium salt is a UVCB substance and therefore was the 10-day windows not evaluated. No toxicity to the inoculum was observed at 1.62 mg a.i./L
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The ready biodegradability of the test substance was determined in four different tests. Coco fatty acids 2 -sulfoethyl ester, sodium salt was found to be readily biodegradable in all four tests. In the key study by van Ginkel, a Closed Bottle test according to the slightly modified OECD, EEC and ISO test guidelines under GLP conditions is described and here already after 14 days 80% degradation was observed. After 28 day 78% degradation was observed. No toxicity to the inoculum was observed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
